JOHN B. BARTHOLOMEW, OF PEORIA, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE SAT'ILEY STAOKER COMPANY, OF INDIAN- APOLIS, INDIANA, A CORPORATION OF MAINE.

STRAW-STCKER.

Speccaton of Letters Patent,

Patented April 17, 1906.

Be it known that I, JOHN B. BARTHoLo- MEW, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Straw-Stackers, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure I is a side view showing the rear portion of a thresher or separator frame and an attached straw-stacking mechanism embodying my invention, the outer stacker-section being shown in full lines in its folded position and in dotted lines in one of its operative positions. Fig. 2 is a similar view showing the outer stacker-section in its extreme elevated operative position.

Referring to the drawings, A indicates the rear portion of a thresher or separator frame, supported by rear ground-wheels B.

A is a supplemental frame extending rearwardly and by preference somewhat upwardly from the thresher-frame and constituting a chamber through which the threshed straw is delivered into an attached straw-receiving device or hood O, by which latter the straw is arrested and delivered downward by gravity to the lower end of the stacker.

B indicates a supporting-frame, attached to and extending rearwardly from the lower part of the frame A and adapted to support by suitable pivoting devices having a vertical axis the lower end of the stacker. The stacker is indicated as a whole by D, and its inner section D is attached to or forms a part of a horizontally-vibrating frame, the lower vertical pivot of which is mounted in or on the frame B', as already described, and the upper vertical pivot of which is mounted in or on the supplemental frame A of the thresher above the straw-delivery means or opening of the latter. It will be understood that these pivots, the lower of which is indicated at a and the upper at a, are arranged in the same vertical line, said line being indicated in Fig. l between the points a and a. The upper part of the inner stacker-section D is connected with said upper pivot a by an inwardly-extending frame member or bars d2, having a bearing d3 for the pivot. The outer or upper stacker-section is indicated at D2 and is hinged to said inner section by a transverse horizontal shaft or pivot d8 and is adapted to be adjusted in vertical planes by a draft device comprising a rope or ropes d, connected at d* with the inner end of the section D2, a suitable windlass or pulleys for said rope or ropes at d5, an actuating-crank d on said windlass or pulleys, --and a ratchet-andpawl locking device (Z7. It will be understood, however, that various means may be employed for taking up and letting off the draft device to adjust or fold the outer stacker-section. The point or points of attachment d4 of the draft device are remote from the hinge at d8 and are so related thereto that during all of the operative positions of said outer section the draft device will act between the point d4 and the taking-up mechanism at d5 on a line which passes to the rear of the hinge d8, whereby for all of its operative or stacking positions the outer stackersection is fully controlled by the draft device from the relatively low point at which the operative mechanism Z5 d is situated and which is within convenient reach of a person standing on the ground, even to the extreme elevated position shown in Fig. 2. When, however, the outer stacker-section is lowered for folding, the line of the draft device will pass across the neutral point or line extending through the take-up device d5 and hinge d8, after which the take-up may be operated to shorten the draft device and draw the section D2 against the rear side of the inner section. When so folded, the section may be secured by a latch d". The draft device by reason of its relation to the section D2 and its hinge thus operates to draw said section in either of two directions.

The straw carrying mechanism of the stacker comprises an inner elevating -belt F, having, preferably, a more or less nearly horizontal lower portion f and a steeply-inclined part f. While the straw-receiving part f and the elevating part f may be independent, each part arranged and operated as a separate belt, I prefer to employ a single belt, as shown, the inner end of which is carried by a roller f 2, the upper end by a roller f 4 at or near the top of the section D, and the intermediate portion of which is guided and deected by rollers f 3f 5 at the lower outer part of said section. The receiving part f is arranged as the bottom of a straw receiving IOO hopper E on the stacker below the deliveryhood C, the parts C and E being substantially concentric with the line a a. With the carrierf cooperates an underacting belt or drag G, carried by lower and upper rollers g g', mounted on the stacker-section D. It will be understood, however, that the principal features of my invention do not depend upon the particular construction of the straw receiving and elevating means, and the parts F and G may be considered as typical of any suitable straw elevator or carrier. The straw delivered between the rollers g f4 is received upon the inner end of a carrier-belt Z, mounted on inner and outer rollers Zc Ze', the latter being journaled in the part K of the outer stacker-section D2, the shaft of the inner roller Zc being substantially concentric with or constituting the hinge (ZS.

The stacker actuating` mechanism comprises, iirst, a vibrating mechanism II, acting to oscillate or vibrate the stacker as a whole on the vertical axis a a. This vibrating mechanism is or may be of known character, actuated by a transmitting mechanism I from a power-shaft d of the thresher, It comprises also a stacker-belt-driving mechanism, of which ZL is a transmitting mechanism taking power continuously from the mechanism H to the roller f 2 of the carrier or elevator F to drive the latter.

A chain-and-s'procket gearing g2 drives the roller g and the belt G from the shaft of roller f3, and the roller 7c and outer carrier Z are driven by a similar gearing Z from the shaft of roller f 2.

The stacker-section D2 is provided with an extreme outer section K, which latter carries the roller 7c of the carrier Z and is adapted to fold upon a transverse hinge 762 against the face of the inner part of said section D2, Fig. l, whereby the down-folding of the long outer section D2 without contact with the ground is permitted.

The considerable height of the section D/ and the hinge d'8, with the corresponding length of the inner or main portion of the stacker-section D2 and the additional length of the extreme outer section K, give great range and stacking capacity to the machine.

It will be understood that the point of attachment (Z4 will be eccentric to or remote from the axis Z8 (somewhat above it) and adapted to move to the rear of the axis as the section swings below the horizontal.

The draft device has its points of attachment so related to the hinge d8 that when the section D2 -is suspended by gravity from said hinge in a substantially vertical position the line of the draft device passes substantially through the axis of the hinge.. This enables the exertion of a very moderate manual force to move the stacker-section outward, so that the draft device may act at the front of the hinge to elevate the section or inward, so that the draft device may act at the rear of the hinge to complete the folding of the section.

I have heretofore patented a straw-stacker carrier composed of two sections hinged together and supported by a rope attachment, such device being shown in my Patent No. 556,487, dated May 17, 1896. The form of the stacker there shown, however, differs radically from that herein claimed in several particulars, among which may be noted the following: The object ofthe earlier invention was to provide a straw-stacker carrier having two or more sections which are adapted to be supported in working position by a rope under such relationship that the steps incident to folding and unfolding could be accomplished without changing the length of the supporting-rope which was in use during such operation, and hence avoiding any winding or unwinding of the rope during the folding. The construction was such as to necessitate a vertical movement of both the lower and upper sections of the carrier whenever the carrier was folded or unfolded. It will thus be seen that there are essential differences between such earlier construction of mine and the construction herein disclosed and claimed, as the present construction requires the winding and unwinding of the supporting-rope during the folding and unfolding operations, whereas the earlier construction was for the purpose of avoiding such winding and unwinding, and in my earlier construction it was necessary that both of the sections of the carrier have a vertical movement relative to each other during the folding or unfolding operations, whereas in my present construction the lower section of the carrier has no vertical movement whatever when the carrier is being folded or unfolded.

I do not claim herein, broadly, a draft device which is adapted to pass across the hingeaxis of the outer section as the latter passes from folded to operating position, or vice versa, that being the subject of my Patent No. 706,214, dated August 5, 1902.

What I claim is- 1. In a straw-stacker, the combination of an inner stacker-section, a support for the same, an outer stacker-section vertically swingable on the inner section on a transverse axis and adapted to fold downward toward the rear of the inner section, and a draft device leading from the outer section to the inner section and connecting the said sections and arranged to pass across said axis of the outer section from the front to the rear of said axis as the outer section turns downward 'and forward, substantially as set forth.

2. In a straw-stacker, the combination of an inner stacker-section, a support for the same, an outer stacker-section vertically swingable on the inner section on a transverse axis and adapted to fold downward at the rear of the inner section, and a draft dc- IOO IIO
